My invention relates to improvements in mops. It is particularly well adapted for washing automobiles.

One of the objects of my invention is to provide the head of a mop of the kind described with novel means for covering with soft material all portions of the head which are adapted in the use of the mop to Contact with the surface which is being washed, and thus eliminate liability of scratching such surface. Y

A further object of my invention is to provide novel and eflicient means for fastening the mop to the mop head, which is simple, cheap, strong, durable, not likely to get out of order, and which enables the quick and easy attachment of the mop to the head.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing which il'- lustrates the preferred embodiment ofmy invention and a modification thereof,

Fig. 1 is a plan view ofa mop head provided with my improvement.

Fig. 2 is an enlarged section on the linev 22 of Fig. 1.

. Fig. 3 is an elevation, partly broken away of the mop head shown in Fig. 2.

Fig. 4 is a plan view, partly breken away,

of the mop head looking at the bottom thereof, the outer mop being omitted.

Fig. 5 is a sectional fragmenta-l view of a modication which employs but a single mop.

Similar characters of reference designate similar parts in the different views.

1 designates the top of a. cuplike mop head provided with a discharge opening 2, Fig. 4, which communicates with a tubular stem 3 adapted for attachment to a hose, not shown.

The mop head is provided with a depending wall 4 provided on its inner side near its top with a circumferential groove 5. The outer side of the wall 4 is provided, below the groove 5 with a circumferential groove 6.

In the form shown in Fig. 2, two mops 7 are shown respectively supported by two pieces of relatively soft sheet material 8 and 9 which respectively extend around and embrace the inner and outer sides of the wall 4 1932..- seriai no. 597,313.

and cover the lower edge of the wall, said two pieces being sewed together below said edge,

so as'to be in effect one sheet.

The inner piece 8 embraces a securing member comprising an eXpansible and contractible resilient wire divided ring 10, Figs. 2 and 4, which is retained in the inner groove 5 by its resiliency and expansibility, and which firmly holds the sheet material 8 against the inner side of the wall 4.

For holding the outer piece of sheet material 9 against the outer side of the wall 4, securing means located in the outer groove 6 is provided, and, as shown, comprises a wire 11 having its ends fastened'together, Fig. 3, and located inthe outer groove 6 in which it engages and holds in said groove the outer piece 9 of sheet material.

In the form shown in Fig. 5, the parts correspond to the form shown in Figs. 1 to 4, eX- ceptingthat but a single mop 7 is employed and the sheet material supporting the mop comprises but a single piece 12 which covers the inner and outer sides and the lower edge of the mep head 4, vsaid piece 12 covering the expansible divided ring 10 and being held by said ring in the inner groove 5, and being held by the wire 11 in the outer groove 6 of the mop head 4.

As both sides and lower edge of the mop head are covered by the soft sheet material 8, in the form shown in Fig. 2 and by the soft sheet material 12 in `the form shown in Fig. 5, there is no liability of the mop head scratching the surface washed.

I do not limit my invention to the structures shown and described, as many other modifications, within the `scope of the appended claims, may be made without depart ing from the spirit of my invention.

`llVhat I claim is 1. ln a mop, an inverted cup-shaped head the depending wall of which is provided with two r grooves extending circumferentially around its inner and outer sides respectively,

mop supporting relatively soft sheet material f covering the inner and outer sides and the lower edge of said wall, an expansible resilient member embraced by and holding said ma- E?V n y 'i 1,879,809

terial in said inner groove, and means for holding said material in said outer groove.

2. In a mop, a head having a peripheral depending Wall provided varound its inner and outer sid-es respectively With a circumferential groove, a mop supporting relatively soft` sheet material covering the inner and outer sides and the loWer edge of said Wall, a resilient expansible and contractible member holding said material in said inner ygroove and retained therein by its resiliency, and means for holding said material against the outer side of said Wall and in said outer groove.

In testimony whereof I aflix my signature.
